  JP 2003-181769 A   JP 2002-58538 A

  With regard to brush bristle materials used for conventional grinding, polishing, surface treatment, cleaning, and deburring of a work surface, for example, technologies having various characteristics as described above are disclosed. However, in Japanese Patent Application Laid-Open No. 2003-181769, the brush material is linear or pipe-shaped, and the cross-sectional shape is round, polygon, clover, cross, or ellipse, The tip of the brush material in contact with the surface and the fur of the root were the same strength. For this reason, it has been difficult to bring a brush material having a thin wire diameter into contact with the surface to be processed with a strong bristles.

  In JP 2002-58538 A, the brush bristle material has a multi-leafed cross-sectional shape and has a sharpened portion, and the sharpened portion is divided into a plurality of branched portions. In order to manufacture the part and the branch part, it was necessary to bundle a large number of cut bristle and to treat one end side thereof with a solvent such as an aqueous caustic soda solution. Therefore, the structure and manufacturing procedure of the bristle material for brushes have a problem that they have a complicated and time-consuming configuration.

  The present invention has been made to solve the above-described problems, and the wire diameter of the bristle material when grinding, polishing, surface treatment, cleaning, or deburring is performed on the work surface. The object of the present invention is to provide a bristle material for a brush that can make a bristle waist strongly contact with the work surface even when it is thin, has high scraping performance on the work surface, and has a simple structure and manufacturing procedure. .

The bristle material for brushes for performing any one of grinding, polishing, surface treatment, cleaning, and deburring according to the present invention is configured as follows.
(1) In the bristle material for a brush for performing any one of grinding, polishing, surface treatment, cleaning, and deburring of a work surface, the bristle material for brush has a cross section having a plurality of core parts. In addition, it is connected with a thickness different from the thickness of the core portion.

  (2) In the bristle material for brush according to (1), the cross section has a coupling portion between the plurality of core portions and the plurality of core portions, and at least one end in the longitudinal direction is divided at the coupling portion. It has been done.

  (3) The bristle material for a brush according to (2) above, wherein the mechanical strength of the material of the coupling portion is different from the mechanical strength of the material of the core portion.

  (4) In the brush bristle material described in (1) to (3) above, at least one of a notch, a hole, an uneven portion, or a stepped portion is formed between the core portions or in the coupling portion. is there.

  (5) In the bristle material for brush according to (1) to (4) above, the bristle material for brush is at least one of grinding abrasive grains, polishing abrasive grains, metal abrasive grains, mineral abrasive grains, and artificial crystal abrasive grains. Are mixed, kneaded, or fixed to the base material, or any of the abrasive grains is fixed by a paint film, a coating film, or a plating film.

  The bristle material for brushes of the present invention can obtain the following effects. In the description, the same reference numerals as those in the claims are attached.

  (1) The bristle material for a brush is formed by connecting a plurality of core portions so that the thickness of the intermediate portion of the core portion and the thickness of the core portion are different. Therefore, compared to the brush bristle material that is not formed so that the wall thickness is different, by setting the difference between the wall thickness of the middle part of the core part and the wall thickness of the core part, It can be set. In addition, for example, even when ultrafine fibers having a diameter of 0.1 mm or less are used, it is possible to strongly set the hair.

  Moreover, since the thickness of the intermediate part of two core parts is formed thinner than the thickness of the core part, the bristle material for brushes has the thickness formed in the intermediate part of the two core parts. The part can be easily divided at one end in the longitudinal direction by cutting or tearing. For this reason, the bristle material for brushes can set the fur and hips other than the tip part in the longitudinal direction strongly, and can flexibly set the fur and hips at the tip part in the longitudinal direction. For this reason, it is possible to strongly set the hair and to bring the tip portion into contact with the work surface very finely. For this reason, for example, a high scraping performance can be exerted on a work surface that requires extremely fine machining. In particular, it is optimal for a work surface requiring deburring. For example, in the case of using ultrafine fibers having a diameter of 0.1 mm or less, it is particularly suitable for a surface to be processed that requires polishing and cleaning processing such as a liquid crystal surface and a glass surface.

  In addition, since the brush bristle has a corner, even when the brush bristle has a thin wire diameter, the bristle can be strongly set by the corner and has high scraping performance against the work surface. Can demonstrate.

  Moreover, since the bristle material for brushes is formed in the long shape which has two core parts in the cross section of a longitudinal direction, a structure is very simple. Therefore, a bristle material for a brush with a simple manufacturing procedure can be produced.

  (2) The bristle material for brushes has a coupling portion having a thickness smaller than the thickness of the core portion formed between the two core portions. Therefore, the breaking strength of the joint portion is set to be weaker than the breaking strength of the core portion. Therefore, for example, by holding and tearing the two core portions with the fingertips, it is possible to form the split portion at one end in the longitudinal direction extremely easily and quickly. Further, even when the use of a cutting tool such as a cutter or a scissors is used, a divided portion can be formed at one end in the longitudinal direction extremely easily and quickly as described above.

  Moreover, since the bristle material for brushes has the split part formed at one end in the longitudinal direction, the fur and hips other than the split part can be set stronger than the fur and hips of the split part. Moreover, a division part can be set thin compared with the wire diameters other than a division part. For this reason, even if the hair material has a thin wire diameter, the brush hair material can be brought into strong contact with the work surface, and the thinly set divided portion can be brought into contact with the work surface very finely. it can. Therefore, for example, it is possible to exhibit a high processing performance without any processing residue on a processing surface that requires extremely fine processing. In particular, it is most suitable for a work surface that requires grinding, polishing, surface treatment, or cleaning.

  In addition, since the bristle material for brushes has corners formed in the core part and corners formed in the divided parts, the corners having strong and low waists against the surface to be processed Can be touched. Therefore, for example, a high scraping performance can be exhibited even on a work surface that requires extremely fine processing. In particular, it is optimal for a work surface requiring deburring.

  (2) As a cross-section of the bristle material for the brush, the core part is formed in a substantially square shape, the corner part is formed, and the joint part is formed on the lower surface between the two core parts without a step. When a cross section is used, the lower surface without a step can scrape the work surface strongly. In particular, it is optimal for a work surface that requires grinding.

  In addition, when a cross-section in which a coupling portion curved in a substantially U-shape is formed between two core portions as a cross-section of the bristle material for the brush, the approximate U-shape of the coupling portion is Since the impact from the surface to be processed can be absorbed, the surface to be processed can be made extremely smooth without causing dents or the like to adhere to the surface to be processed. In particular, it is optimal for a surface to be processed that requires polishing or surface treatment.

  In addition, when the cross-section of the bristle material for brush is a cross-section in which three coupling parts are formed on the outer periphery of the hole part via three core parts, the bristle material for brush has a hole part. Since the substantially cylindrical shape is formed, the outer diameter of the brush bristle material can be set large even if it is lightweight. Moreover, since the hole is formed, it is possible to absorb an impact from the surface to be processed. Therefore, dents and the like are not attached to the work surface. In particular, it is optimal for the surface to be processed that requires cleaning.

  In addition, as a cross-section of the brush bristle material, when adopting a cross-section in which three core parts are formed via two coupling parts so as to be approximately V-shaped, The approximately V-shape formed in the cross section can strike the surface to be processed. Therefore, it is possible to remove the surface, dirt, flash, etc. of the surface to be processed by powerful hitting. In particular, it is optimal for a surface to be processed that requires surface treatment, cleaning, or deburring.

  (3) The bristle material for brushes is set so that the mechanical strength of the material of the joint portion is weaker than the mechanical strength of the material of the core portion. Therefore, it is possible to divide the connecting portion very easily. Without adopting a method of tearing with a fingertip, a method of using a cutting tool such as a cutter or a scissors, for example, a method of lightly brushing a brush hair material, a method of lightly pressing, a method of tapping lightly, etc. can be employed.

  Further, as another embodiment, when a bristle material for a brush is used in which the mechanical strength of the material of the joint portion is set stronger than the mechanical strength of the material of the core portion, the joint portion is The core portion can be held strongly, and when the coupling portion is divided, it is possible to prevent the split tearing from proceeding easily.

  As another embodiment, a coupling portion is formed at the center of the three core portions, and the mechanical strength of the material of the coupling portion is weaker than the mechanical strength of the material of the core portion. When the set brush bristle material is employed, the coupling portion can be divided very easily, and the three divided core portions can be formed radially. Therefore, it is possible to make contact with the surface to be processed without unevenness. In particular, it is most suitable for a processed surface that requires polishing and cleaning of a liquid crystal surface, a glass surface, and the like.

  (4) When a bristle material for brushes in which a plurality of notches are formed at predetermined intervals in parallel with the longitudinal direction is used for the joint portion, the joint portion is torn along the notches for use purposes. A divided portion having an optimal length can be formed. Further, since the notches are formed, the connecting portion can be divided very easily.

  Further, as another embodiment, when a bristle material for a brush having a plurality of holes formed at a predetermined interval is adopted as the coupling portion, the interval, shape, etc. where the holes are formed are arbitrary. By setting to, the tear resistance of the joint can be set.

  Also, as another embodiment, when a brush bristle material with irregularities formed in the joint is adopted, the optimum strength according to the purpose of use can be set by setting the height of the irregularities. Can be formed.

  As another embodiment, when a brush bristle material having a step is formed in the coupling portion, the coupling portion can be accurately divided at the level difference.

  (5) The bristle material for brushes has abrasive grains mixed or kneaded into the base material. Therefore, the corner and abrasive grains can be brought into contact with the surface to be processed. Therefore, the bristle material for brushes can exhibit high processing performance such as grinding, polishing, surface treatment, cleaning, or deburring. Further, since the abrasive grains are mixed or kneaded, the abrasive grains can be brought into contact with the surface to be processed even when the substrate is worn.

  In another embodiment, when a brush bristle material with abrasive grains fixed to the base material is used, the abrasive grains can be fixed easily and quickly on the surface of the base material. It is inexpensive and can exhibit high processing performance.

  Further, as another embodiment, when a brush bristle material in which a film is formed on the surface of the base material and the abrasive grains are fixed on the film is used, the film causes the abrasive grains to fall off. In addition to being able to prevent or suppress the wear of the substrate, it is possible to prevent or suppress the wear of the base material, so that the brush bristle material can have high durability.

  Even when grinding, polishing, surface treatment, cleaning, or deburring is performed on the work surface, even if the wire diameter of the bristle material is thin, the fur waist can be brought into strong contact with the work surface. Along with the purpose of providing a brush hair material that has high scraping performance on the work surface and that has a simple structure and manufacturing procedure, any one of grinding, polishing, surface treatment, cleaning, and deburring of the work surface In the bristle material for brushes for processing, the bristle material for brushes is realized in a configuration in which a cross section having a plurality of core parts is formed and connected with a thickness different from the thickness of the core parts. did.

  As shown in FIG. 1, the brush bristle material 1 of the present invention used when grinding, polishing, surface treatment, cleaning, or deburring is performed on the surface to be processed. The core part 2 is formed in a substantially rectangular shape having corner parts 3. Moreover, the bristle material 1 for brushes is formed by connecting two core portions 2 so that the thickness 4 and the thickness 5 are different. Further, the thickness 4 of the middle part of the two core parts 2 is formed thinner than the thickness 5 of the core part 2.

  Moreover, the bristle material 1 for brushes can also be divided at one end in the longitudinal direction by cutting or tearing a portion having a thickness 4 formed in the middle part of the two core parts 2. As a means for dividing, use of a cutting tool such as a cutter or scissors, or a method of tearing the core 2 by holding it with a fingertip, for example, can be adopted as appropriate.

  Moreover, the bristle material 1 for brushes can employ | adopt various materials. For example, synthetic resin, thermoplastic resin, thermosetting resin, synthetic resin foam, thermoplastic elastomer, synthetic fiber, synthetic rubber, non-ferrous metal plate or wire, metal plate or wire, etc. Can be adopted. Various chemical fibers can be set and used in a timely manner according to the purpose of use. A chemical fiber is a fiber produced by chemical synthesis or processing from petroleum, coal, etc., and includes synthetic fiber, fiber with abrasive material, conductive composite fiber, inorganic fiber, recycled fiber, and semi-synthetic fiber. Synthetic fibers are fibers spun from a synthetic polymer compound, and include synthetic fibers such as fluorine-based, polyamide-based, polyvinyl chloride-based, polypropylene-based, polyethylene-based, and aramid-based fibers. Abraded fibers include, for example, various minerals such as silicon carbide, alumina and diamond, and materials having grinding performance such as silica and ceramic, which are attached to, kneaded with, or mixed with the fibers of the base material such as nylon and PBT. It is a formed fiber.

The surface treatment is a process for improving the state of the surface to be processed, such as curing, beautifying, smoothing, and corrosion resistance the surface of the surface to be processed. The cleaning is a process of cleaning the surface of the processing surface with a brush. Deburring is a process of removing an excess portion formed on the edge of a product by brushing with a brush.

  Another embodiment of the brush bristle material will be described. The bristle material for brushes according to another embodiment is formed in a long shape having a cross section as shown in FIGS. (A) The bristle material 11 for brushes has a core portion 12 formed in an approximately round shape, corner portions 13 are formed, and two core portions 12 have a wall thickness 14 and a wall thickness 15. Are connected so as to be different. The brush bristle material (B) has a total of four core portions 22 and core portions 26 having different shapes, corner portions 23 are formed, and the core portion 22 and the core portion 26 are made of meat. The thickness 24 and the wall thickness 25 are formed so as to be different from each other. In the bristle material 31 for brush (C), four core portions 32 are formed on the outer periphery of the hole portion 37, corner portions 33 are formed, and the core portion 32 has a thickness of 14 and meat. The thicknesses 15 are connected so as to be different. (D) The bristle material 41 for a brush has a core portion 42 formed in a substantially round shape, a plurality of protrusions 47 having corner portions 43 are formed, and the two core portions 42 are made of meat. The thickness 44 and the wall thickness 45 are formed so as to be different from each other. Further, as shown in FIGS. 9A to 9F, the brush bristle material according to another embodiment has a core portion 202, 212, 222, 232, 242, or 252 and the meat of the core portion. Brush bristle materials 201, 211, 221, 231, 241, or 251 having cross-sections connected with a thickness different from the thickness can also be employed.

  Since the bristle material for brushes described in Example 1 is configured as described above, the bristle material for brushes 1 is connected so that a plurality of core portions 2 have different thicknesses 4 and 5. Is formed. Therefore, as compared with a bristle material for a brush that is not formed so as to have different wall thicknesses, it is possible to set the hair and waist strongly by arbitrarily setting the difference between the wall thickness 4 and the wall thickness 5. In addition, for example, even when ultrafine fibers having a diameter of 0.1 mm or less are used, it is possible to strongly set the hair.

  Further, since different thicknesses 4 and 5 are formed, and the thickness 4 of the middle part of the two core parts 2 is formed thinner than the thickness 5 of the core part 2, A portion having a thickness of 4 formed in the middle portion of the core portion 2 can be easily divided at one end in the longitudinal direction by cutting or tearing. Therefore, the bristle material 1 for brushes can set the fur and hips other than the front-end | tip part of a longitudinal direction strongly, and can set the fluff of the front-end | tip part of a longitudinal direction flexibly. For this reason, it is possible to strongly set the hair and to bring the tip portion into contact with the work surface very finely. For this reason, for example, a high scraping performance can be exerted on a work surface that requires extremely fine machining. In particular, it is optimal for a work surface requiring deburring. For example, in the case of using ultrafine fibers having a diameter of 0.1 mm or less, it is particularly suitable for a surface to be processed that requires polishing and cleaning processing such as a liquid crystal surface and a glass surface.

  In addition, since the brush bristle material 1 is formed with the corners 3, even when the brush bristle material 1 has a thin wire diameter, the bristle can be strongly set by the corners 3 and the surface to be processed is High scraping performance can be demonstrated.

  Moreover, since the bristle material 1 for brushes is formed in the elongate shape which has the two core parts 2 in the cross section of a longitudinal direction, a structure is very simple. Therefore, the bristle material 1 for brushes with a simple manufacturing procedure can be manufactured.

  Although the bristle material 1 for brushes of Example 1 is configured as described above, the number of core parts and the cross-sectional shape can be arbitrarily selected in addition to the above. Moreover, about the formation state of a corner | angular part, the structure that a corner | angular part may be formed by dividing | segmenting the thick part formed in the intermediate part of the core part may be sufficient. Therefore, it may be a case where corner portions are not formed in a non-divided cross section, as in the case where a substantially round shape is adopted as the plurality of core portions.

  Example 2 is shown in FIGS. FIG. 3 is a perspective view of the bristle material for brushes of the present invention as seen from the front side. In FIG. 3, 51 is a brush bristle material, 52 is a core part, 53 and 60 are corner parts, 54 and 55 are thick, 58 is a joint part, and 59 is a split part. FIG. 4 is a cross-sectional view of another embodiment of the brush bristle material of FIG. In FIG. 4, 61, 71, 81 and 91 are brush hair materials, 62, 72, 82 and 92 are core parts, 63, 73, 83 and 93 are corner parts, 64, 65, 74, 75, 84 and 85. 94 and 95 are wall thicknesses, 87 is a hole, and 99 is an angle.

  As shown in FIG. 3, the brush bristle material 51 of the second embodiment is formed in a long shape having two core portions 52 in the longitudinal section, and the core portion 52 is a substantially square shape having corner portions 53. It is formed into a shape. A coupling portion 58 is formed between the two core portions 52. In addition, the two core portions 2 are formed so as to be connected so that the thickness 4 and the thickness 5 are different from each other, and at one end in the longitudinal direction, a divided portion 59 in which the coupling portion 58 is divided is formed. is there.

  The brush bristle material 51 has a corner portion 53 formed in the core portion 52 and a corner portion 60 formed in the divided portion 59. Further, the thickness 54 of the coupling portion 58 is formed thinner than the thickness 55 of the core portion 52.

  Another embodiment of the brush bristle material will be described. The bristle material for brushes according to another embodiment is formed in a long shape having a cross section as shown in FIGS. The bristle material 61 for brush (A) has a core portion 62 formed in a substantially square shape, corner portions 63 formed, and a wall thickness 64 between the two core portions 62. While being thinner than the thickness 65, there is no step on the lower surface, and a coupling portion 68 is formed. In the bristle material 71 for brush (B), the core part 72 is formed in a substantially triangular shape, the corner part 73 is formed, and the wall thickness 74 is between the two core parts 72. A coupling portion 78 that is thinner than the thickness 75 and curved in a generally U-shape is formed. (C) The bristle material 81 for brushes has three different core portions 82 formed on the outer periphery of the hole portion 87 and corner portions 83, and between the core portions 82, The thickness 84 is thinner than the wall thickness 85, and three coupling portions 88 are formed on the outer periphery of the hole portion 87. The brush bristle material 91 of (D) has three substantially hexagonal core portions 92 formed therein, corner portions 93 are formed, and a wall thickness 94 is between the core portions 92. Two coupling portions 98 are formed so as to be thinner than the thickness 95 and to be approximately V-shaped at an angle 99.

  Since the brush bristle material described in Example 2 is configured as described above, the brush bristle material 51 is thinner than the wall thickness 55 of the core part 52 between the two core parts 52. A connecting portion 58 having a wall thickness 54 is formed. Therefore, the breaking strength of the joint portion 58 is set to be weaker than the breaking strength of the core portion 52. Therefore, for example, by holding and tearing the two core parts 52 with the fingertips, the split part 59 can be formed at one end in the longitudinal direction very easily and quickly. Further, even when the use of a cutting tool such as a cutter or a scissors is used, the divided portion 59 can be formed at one end in the longitudinal direction very easily and rapidly as described above.

  Moreover, since the bristle material 51 for brushes has the split part 59 formed at one end in the longitudinal direction, the fur waist other than the split part 59 can be set stronger than the fur waist of the split part 59. Further, the dividing portion 59 can be set thinner than the wire diameter other than the dividing portion 59. Therefore, even if it is a bristle material with a thin wire diameter, the bristle material 51 for brushes can be made to contact a process surface strongly, and the division part 59 set thinly is made to contact a process surface very finely. I can do things. Therefore, for example, it is possible to exhibit a high processing performance without any processing residue on a processing surface that requires extremely fine processing. In particular, it is most suitable for a work surface that requires grinding, polishing, surface treatment, or cleaning.

    Further, the brush bristle material 51 has the corner portion 53 formed in the core portion 52 and the corner portion 60 formed in the divided portion 59. It is possible to make the corner 60 having a weak fur contact. Therefore, for example, a high scraping performance can be exhibited even on a work surface that requires extremely fine processing. In particular, it is optimal for a work surface requiring deburring.

  Further, as shown in (A), as a cross-section of the bristle material for the brush, the core portion 62 is formed in a substantially square shape, the corner portion 63 is formed, and the lower surface between the two core portions 62 is formed. When a cross-section in which the coupling portion 68 is formed without a step is adopted, a lower surface without a step can strongly scrape the processing surface. In particular, it is optimal for a work surface that requires grinding.

  Further, when the cross section of the bristle material for the brush is a cross section in which a coupling portion 78 curved in a substantially U shape is formed between the two core portions 72 as shown in FIG. Since the approximate U-shape of the portion 78 can absorb impacts and the like from the surface to be processed, the surface to be processed can be made extremely smooth without attaching dents or the like to the surface to be processed. In particular, it is optimal for a surface to be processed that requires polishing or surface treatment.

  In addition, when the cross section of the bristle material for brush is a cross section in which three coupling portions 88 are formed on the outer periphery of the hole portion 87 via the three core portions 82 as shown in (C). Since the brush bristle material has a generally cylindrical shape having a hole 87, the outer diameter of the brush bristle material can be set large even if it is lightweight. Moreover, since the hole part 87 is formed, the impact etc. from a to-be-processed surface can be absorbed. Therefore, dents and the like are not attached to the work surface. In particular, it is optimal for the surface to be processed that requires cleaning.

  In addition, when the cross-section of the bristle material for the brush is a cross-section in which three cores 92 are formed through two coupling parts 98 so as to be approximately V-shaped as shown in (D). The brush bristle material has a generally V-shaped cross section formed so that it can strike the surface to be processed. Therefore, it is possible to remove the surface, dirt, flash, etc. of the surface to be processed by powerful hitting. In particular, it is optimal for a surface to be processed that requires surface treatment, cleaning, or deburring.

  The brush bristle material 51 of the second embodiment is configured as described above, but the divided portion can be formed at both ends in addition to one end in the longitudinal direction as described above. The dividing unit 59 can be arbitrarily set as long as the combining unit 58 is divided. For example, the dividing part 59 described in the second embodiment is divided into two parts having the core part 52. However, by dividing the coupling part 58 into a plurality of parts in parallel to the longitudinal direction, the two core parts 52 and the plurality of parts are divided. It can be divided into a plurality of divisions consisting of divided coupling portions.

  Example 3 is shown in FIG. FIG. 5 is a cross-sectional view of the brush bristle material of the present invention. In FIG. 5, reference numerals 101, 111, and 121 denote brush hair materials, reference numerals 102, 112, and 122 denote core parts, and reference numerals 103, 113, and 123 denote corner parts.

  As shown in FIG. 5A, the brush bristle material 101 according to the third embodiment has two substantially round core portions 102 having corner portions 103 in the cross section, and is coupled between the core portions 102. A portion 108 is formed. Further, the mechanical strength of the material of the coupling portion 108 is set weaker than the mechanical strength of the material of the core portion 102.
